时钟AnalogClock与DigitalClock

1. 获得当前年月日时分

        Calendar cal = Calendar.getInstance();
        year = cal.get(Calendar.YEAR);
        month = cal.get(Calendar.MONTH);
        day = cal.get(Calendar.DAY_OF_MONTH);
        hour = cal.get(Calendar.HOUR);
        minute = cal.get(Calendar.MINUTE);

2.初始化DatePicker组件，指定监听

        // 初始化datepicker组件，指定监听
        datePic.init(year, month, day, new OnDateChangedListener() {

            @Override
            public void onDateChanged(DatePicker view, int year,
                    int monthOfYear, int dayOfMonth) {
                // TODO Auto-generated method stub
                AndroidAnalogClockActivity.this.year = year;
                AndroidAnalogClockActivity.this.month = monthOfYear;
                AndroidAnalogClockActivity.this.day = dayOfMonth;
                showDate(year, monthOfYear, dayOfMonth, hour, minute);
            }
        });

3.指定TimePicker监听

        timePic.setOnTimeChangedListener(new OnTimeChangedListener() {
            
            @Override
            public void onTimeChanged(TimePicker arg0, int hour, int minute) {
                // TODO Auto-generated method stub
                AndroidAnalogClockActivity.this.hour=hour;
                AndroidAnalogClockActivity.this.minute=minute;
                showDate(year, month, day, hour, minute);
            }
        });

4.显示方法

    // 在EditText中显示
    private void showDate(int year, int month, int day, int hour, int minute) {
        EditText txtShow = (EditText) this.findViewById(R.id.txtShow);
        txtShow.setText("选择的日期：" + year + "年" + (month+1) + "月" + day + "日" + hour
                + "时" + minute + "分");
    }

注意：获得的月份是从0开始的，因此实际月份要+1
